Patented Aug. 22, 1933 UNITED STATES PATENT OFFICE WEATHER EXCLUDING DEVICE FOR CLOSURES John Caldwell Muir, Carluke, and Robert London, Oleland, Scotland 1 Claim.

This application is a division of application Ser. No. 510,828, filed January 23, 1931.

Our invention relates to a draught, dust, and weather excluding device for casement windows and doors, of the kind comprising a member mounted loosely on the sill and adapted to be turned into an operative position by means provided on the window or door, on the closing of same and the object of this invention is inter alia simplicity in fitting and adjustment, cheapness and efficiency, and inability to get out of order.

According to this invention, we provide in the case-sill a hinged-plate having at the opening side thereof a snug or striker suitably fixed thereto, or integral therewith. On the bottom of the outside of window-sash there is suitably attached a storm-plate. A suitable casement fastener having a knob or handle is also provided to secure the sash when closed.

In order that our invention may be properly understood and readily carried into effect, we have hereunto appended two sheets of drawings, of which Figure 1 is a front elevation of a lower window sash looking from the outside.

Figure 2 is a part View in section of bottom sill and sash.

Figure 3 is a similar view to Figure 2, but with sash shown in open position.

Referring to the drawings, A is the casement, and A the easement sides, and B the hingedplate fastened to the sill A with hinges B with snug or striker C. E is the storm-plate which is suitably attached to the window-sash D, and F is the fastener.

The modus operandi is as follows:

Assume the lower casement window D is closed, and it is desired to open same inwards, it is unlocked or unfastened by undoing the fastener F, and the window is pulled inwards on its hinges G.

This action causes the hinged-plate B to turn on its pivot down or over, see Figure 3. When the window D is being closed, this hinged-plateB lying in the turned-down or over-position, the storm-plate E, which is connected with the window D, knocks against the snug or striker C, which is attached to the hinged-plate B, raising the hinged-plate B to its upright or normal position, when the storm-plate E automatically overlaps and presses against the hinged-plate B, thus making the window D at the bottom storm-proof, water-proof, and dust-proof, see Figure 2.

It is to be understood that, although we have only shown our invention as applied to a window, it is equally applicable as a draught excluder to a door from outside.

We claim:

The combination with a window frame and a window sash hinged therein and having its base rail cut along its bottom face to provide a recess and a projecting flange, a storm plate comprising a fiat strip attached to rest flush along the front face of the base rail with is lower edge extending downwardly into the recess, the said window frame having a recess therein in register with the recess in the window sash to form a pocket, a hinged plate mounted on the window frame with its upper edge engaging the lower edge of the storm plate to provide an upright wall closing the pocket, a striker arm attached to said hinged plate to engage the storm plate upon movement of the same, a stop plate attached to the inner wall of the pocket and projecting upwardly therefrom to engage the flange on the window sash in closed position and limit the inward movement of the hinged plate to keep the striker arm in the path of the storm plate, and means carried by the window frame and window sash to hold the parts in closed position.
